Apologies if I’m posting out of turn as I’m new to Rock Pi (though have a couple of other SBCs). Recently received my new 4B+. I’m finding the board won’t boot. I get a solid green light which my searching of this forum tells me means that it can’t find a boot record - but I thought this came preinstalled with TwisterOS? The HDMI gives me no output at all - I’ve tried multiple cables. I bought my own PD supply as Allnet offered no supply for the UK, I’m guessing this might have something to do with it, but the supply I bought complies with the specification.
Additionally I’m finding when I plug the USB in, it’s random whether the green light comes on or not - and the more I’ve been trying, the more often it doesn’t.
Being new to the Rock I’m not entirely sure what I should be expecting, but I did watch a few youtube videos on it and it seemed to be pretty much plug and play. What am I doing wrong?
Thanks in advance!
